Answer:
2(3x + 7)(2x - 1)
Step-by-step explanation:
You can see it a little easier if you take out a common factor of 2
2(6x^2 + 11x - 7)
The 6 leaves you with a lot of factors, the 7 does not. It only has 2 factors.
Let 6 factor into 2 and 3 and the 7 into 7 and 1
2(3x - 1 )(2x + 7)
Now remove the brackets.
2(6x^2 + 21x - 2x - 7) This obviously does not work but we'll combine like terms anyway.
2(6x^2 + 19x - 7)
So we'll try it again
2(3x + 7)(2x - 1)
2(6x^2 + 14x - 3x - 7) Looks like we have it.
2(6x^2 + 11x - 7)
So the right factors are
2(3x + 7)(2x - 1)

Answer:
x= 35000
y= 19000
Step-by-step explanation:
The investment in this question divided into two parts, first who earns 5.5% interest(X) and second who have 4% interest (Y).
The total interest gained is $2685 so you can get this equation.
0.055 x + 0.04 y = 2685
Both x and y sum is $54,000 so you can get this equation
x + y = 54,000
y=54000- x
If you combine both equations
0.055 x + 0.04 y = 2685
0.055 x + 0.04 (54000- x) = 2685
0.055 x + 2160- 0.04x = 2685
0.015x= 2685- 2160
0.015x= 525
x=35000
y=54000- x
y= 54000-35000
y=19000
